Question

A manufacturer makes decorative globes out of silver in the shape of a solid sphere. Suppose each sphere has a radius of 3 cm. If silver is priced at $7.00 per cm", how much will the silver cost to make one solid sphere?

Use 3.14 for , and do not round your answer.

Answer 1

Answer:
`\$791.28`

Explanation:

Given

The radius of the sphere is 3 cm

Silver cost
`\$7` per
`cm^3`

The volume of a sphere is
`(4\pi)/(3)r^3`

Put the values

`\Rightarrow (4\pi)/(3)* 3^3\\\\\Rightarrow (4* 3.14)/(3)* 3* 3^2\\\\\Rightarrow 113.04\ cm^3`

The price of this sphere is

`\Rightarrow 113.04* 7=\$791.28`
